         4 . The system ( 1 ) according to  claim 1 , characterised in that the communication unit ( 12 ) is configured for addressing memory regions on external units ( 2 ,  3 ) according to a standard format for all external units ( 2 ,  3 ), in particular SQL format. 
     
     
         5 . The system ( 1 ) according to  claim 1 , characterised in that a data structure database ( 22 ) is provided, in which data structures ( 26 ,  27 ,  28 ,  29 ,  35 ,  36 ,  37 ,  38 ) of external units ( 2 ,  3 ) connectable to the system are stored. 
     
     
         6 . The system ( 1 ) according to  claim 1 , characterised in that means for checking a data compatibility, in particular with regard to a data format and/or a data width, are provided between elements of the data structure database ( 22 ) and elements of the communication channel database ( 21 ,  24 ,  25 ,  102 ,  104 ,  105 ,  106 ,  107 ). 
     
     
         7 . The system ( 1 ) according to  claim 1 , characterised in that a connection database ( 23 ) is provided in which desired compatible pairs of elements of the data structure database ( 22 ) and elements of the communication channel database ( 21 ,  24 ,  25 ,  102 ,  104 ,  105 ,  106 ,  107 ) are stored. 
     
     
         8 . The system ( 1 ) according to  claim 1 , characterised in that a link database is provided for storing links between process data from a process database ( 3 ) and measurement data from a technical control unit ( 2 ) for the purpose of visualising said data. 
     
     
         9 . A method for monitoring, control and data acquisition of technical processes by means of bidirectional data exchange with external units ( 2 ,  3 ), characterised in that data exchange is carried out with at least one external electronic process database ( 3 ) and at least one external technical control unit ( 2 ). 
     
     
         10 . The method according to  claim 9 , characterised in that each external unit ( 2 ,  3 ) is addressed by means of a unique identifier, wherein identifiers for process databases ( 3 ) are formed from their primary key and identifiers for control units ( 2 ) are formed from a memory address. 
     
     
         11 . The method according to  claim 9 , characterised in that identifiers for data exchange with external units ( 2 ,  3 ) are stored before the beginning of monitoring, control and data acquisition in a communication channel database ( 21 ,  24 ,  25 ,  102 ,  104 ,  105 ,  106 ,  107 ). 
     
     
         12 . The method according to  claim 9 , characterised in that memory regions on external units ( 2 ,  3 ) are addressed according to a standard format for all external units ( 2 ,  3 ), in particular SQL format.
